Field Guide

Easily Missouri’s most valuable tree, the black walnut provides the finest wood in the world, as well as delicious nuts. Both are in high demand and thus form an important part of Missouri’s economy.

Colonies of smooth sumac are most noticeable in early autumn, because the leaves turn brilliant red! You can make drinks and jellies from the clusters of fuzzy red berries.

Amur corktree is a non-native tree that is becoming naturalized in our state. Originally introduced for landscape planting, it has proven itself invasive in the northeastern United States and has shown invasive tendencies in St. Louis.

Bald cypress is an “evergreen” tree that is not evergreen! Like the leaves of hardwoods, its needles turn yellow in the fall and are shed. A tree associated with swamps, its impressive form also graces many public landscapes.

Its range and interesting, variable leaf shapes identify water oak. Like many species that require wet lowland forests, water oak has been declining in our state due to long-term extensive disruption of natural habitats in our Bootheel counties.

Post oak has long been favored for fence posts and was valued by American pioneers. It has distinctive cross- or ghost-shaped leaves. It grows in rocky upland woodlands and in flatwoods on broad ridges.

Overcup oak is fairly easy to identify. The acorns are almost completely covered by their knobby cups. The leaves have long, narrow lobes and wide sinuses. In Missouri, it grows naturally only in wet forests along the Mississippi and Meramec rivers.

A beautiful tree, swamp white oak features bicolored leaves that are shiny, dark green above and downy white below. When a breeze sets them in motion, their wavy or lobed shapes add a calm grace to a summer's hike.

Scarlet oak is a common tree of the Missouri Ozarks. Today it occupies much the same area that shortleaf pine used to dominate before it was extensively cut prior to the 1920s.

This tree has two names as well as two leaf types! In Missouri, southern red oak, or Spanish oak, occurs natively only in our southeast and southernmost counties.
